6.3 Controlled Drugs Legislation & Misuse of Drugs Regulations
Quick Reference: Controlled drugs in Ireland are governed by the Misuse of Drugs Acts 1977 to 2016 and the secondary Misuse of Drugs Regulations 2017 (S.I. No. 173/2017). These statutes control the production, prescription, custody, record-keeping, and destruction of habit-forming or dangerous controlled substances.
Classification of Controlled Drugs (Schedules 1 to 5)
S.I. No. 173/2017 categorizes controlled substances into five schedules, applying progressively strict controls based on medical utility and potential for harm:
| Schedule | Medical Use & Description | Examples | Primary Legal Controls |
|---|---|---|---|
| Schedule 1 | No recognized medical use in standard practice. Production, supply, and possession prohibited without Ministerial license. | Raw opium, coca leaf, LSD, MDMA, synthetic cannabinoids. | Full prohibition; research license only. |
| Schedule 2 | Highly potent opioids and stimulants with major therapeutic utility but high abuse potential. | Morphine, oxycodone, methadone, fentanyl, pethidine, methylphenidate, amphetamines. | CD Register entry required; safe custody cabinet required; strict prescription format; 14-day validity; NO repeats; witnessed destruction of stock. |
| Schedule 3 | Moderate-risk central nervous system depressants, stimulants, and specific opioids. | Buprenorphine, temazepam, flunitrazepam, phenobarbital, pentazocine. | Safe custody cabinet required; strict prescription format (words & figures); 14-day validity; NO repeats; CD Register NOT generally required (except buprenorphine/temazepam record requirements). |
| Schedule 4 | Part 1: Benzodiazepines (e.g., diazepam, alprazolam, nitrazepam).<br>Part 2: Z-drugs (e.g., zopiclone, zolpidem). | Diazepam, lorazepam, zopiclone, zolpidem, pregabalin. | 14-day prescription validity; specific prescription details required; no emergency supply at patient request; safe custody cabinet NOT legally required. |
| Schedule 5 | Low-concentration preparation of certain controlled drugs with minimal abuse potential. | Codeine cough syrups (<0.1% concentration), Kaolin & Morphine mixture. | Exempt from most CD restrictions; standard OTC or POM prescription rules apply. |
Strict Prescription Requirements for Schedule 2 & 3 Controlled Drugs
Under Regulation 15 of S.I. No. 173/2017, a prescription for a Schedule 2 or Schedule 3 Controlled Drug must satisfy exacting statutory criteria. If ANY required element is omitted, the prescription is legally invalid and cannot be dispensed:
- Indelible Ink / Computerized Print: Written in ink or printed format signed by the prescriber.
- Patient Details: Full name and residential address of the patient.
- Patient Age / Date of Birth: Mandatory specification of age if under 12 years.
- Prescriber Details: Name, registration number, address, and signature of prescriber.
- Drug Form & Strength: Exact pharmaceutical form (e.g., modified-release tablets) and strength (e.g., 10mg).
- Total Quantity in Words AND Figures: The total quantity of the drug or number of dosage units MUST be written in both words and figures (e.g., "Sixty (60) tablets" or "300mg (three hundred milligrams)").
- Exact Dose & Frequency: Clear directions (e.g., "Take one tablet twice daily"). Expressions like "Take as directed" or "PRN" without maximum daily dose are legally invalid.
- Instalment Dispensing Directions: If the CD is to be dispensed in instalments (e.g., daily methadone or weekly oxycodone), the prescription MUST state: the exact instalment amount, interval between instalments, and exact dates for dispensing.
Legal Validity & Repeats:
- 14-Day Validity: Prescriptions for Schedule 2, 3, and 4 CDs are legally valid for a maximum of 14 days from the date of signing.
- PROHIBITION OF REPEATS: Prescriptions for Schedule 2 and Schedule 3 Controlled Drugs CANNOT be repeated. A new prescription is legally required for each supply.
Schedule 2 Controlled Drugs Register Management
Under Regulation 27 of S.I. 173/2017, every retail pharmacy business MUST maintain a bound Controlled Drugs Register (or an approved electronic CD register with an immutable audit trail) dedicated exclusively to Schedule 2 drugs.
Mandatory CD Register Rules:
- Separate Sections: A separate section or page must be allocated for each drug, strength, and pharmaceutical form (e.g., Morphine 10mg/ml Oral Solution vs Morphine 10mg MST Tablets).
- 24-Hour Entry Rule: Entries for both receipts (from wholesalers) and supplies (dispensed to patients) must be recorded on the date of transaction or within 24 hours.
- Entry Details: Date, patient/supplier name and address, prescriber details, quantity received/supplied, and the updated running physical stock balance.
- Correction Protocol: Erasures, white-out fluid, or liquid paper are STRICTLY PROHIBITED. Errors must be corrected by a signed and dated footnote or marginal note, leaving the original entry legible.
- Physical Stock Audit: The Supervising Pharmacist must conduct regular physical stock reconciliations (e.g., monthly) against the register balance. Discrepancies must be investigated immediately and reported to the PSI and Gardaí if theft is suspected.
Safe Custody Requirements (S.I. No. 321/1982)
Under the Misuse of Drugs (Safe Custody) Regulations 1982 (S.I. No. 321/1982), all Schedule 2 and Schedule 3 Controlled Drugs MUST be kept in a locked safe or cabinet that complies with Irish Standard I.S. 267.
Key Safe Custody Specifications:
- Constructed of heavy-gauge steel and secured to a solid concrete wall or floor with rawl bolts.
- Fitted with a high-security key or electronic combination lock.
- Kept locked at all times when not actively depositing or removing controlled drugs.
- Keys to the CD safe must remain in the personal custody of the registered pharmacist on duty.
Destruction Protocols for Controlled Drugs
Irish law establishes distinct legal procedures for destroying expired/damaged pharmacy stock versus patient-returned controlled drugs:
1. Destruction of Pharmacy Stock (Schedule 2 CDs)
- Pharmacy stock of Schedule 2 CDs CANNOT be destroyed casually by pharmacy staff.
- Destruction MUST be witnessed by an Authorized Officer appointed by the Minister for Health (e.g., PSI Inspector, Garda Inspector, or Department of Health Inspector).
- Procedure: The drug is rendered denatured/unusable using a CD denaturing kit in the presence of the Authorized Officer. Both the pharmacist and the Authorized Officer must sign the entry in the Controlled Drugs Register verifying the date, quantity, and destruction.
2. Destruction of Patient-Returned Controlled Drugs
- Patients frequently return unused CDs to pharmacies for safe disposal.
- Returned CDs MUST NOT be re-entered into pharmacy stock or recorded in the official CD Register running balance.
- Procedure: Patient returns must be recorded in a separate Patient Returns CD Log, stored securely in the CD safe, and denatured by a pharmacist (witnessed by another pharmacy staff member) before disposal via an authorized hazardous waste contractor.
